NitroPep's antimicrobial technology is helping to combat antimicrobial resistance in the medical sector

NitroPep's Antimicrobial Technology

Nitropep antiviral air filtersNitroPep's antimicrobial technology effectively kills pathogens and works effectively on regularly-handled surfaces, including door handles and grab rails.

Our technology prevents surface colonisation and biofilm formation on metal and plastic surfaces, ensuring that surface ‘recontamination’ and onward transmission of bacteria can be prevented.

NitroPep’s combined result of surface modification renders any treated surface bactericidal. This is done with two key methods:

  1. A bespoke surface engineering process to activate the surfaces
  2. Dip-coating the activated surfaces with an antimicrobial agent

Today there are few public health issues of greater importance, worldwide, than the spread of bacteria and virus such as MRSA, E. coli, Staphylococcus aureus, Salmonella, fungi and other HAIs.

The special NitroPep antimicrobial coating ensures plastic and metal surfaces are protected from the spread of such pathogens, thanks to the coating’s ability to "lock in" disinfectant and antimicrobial actives.

SARS-CoV-2 and COVID-19

NitroPep has independently-assessed laboratory data that shows that our covalently bonded coating using chlorhexidine kills SARS-CoV-2, the virus that causes COVID-19, along with gram-negative and gram-positive bacteria and fungi. A summary of this study report can be provided on request.

Antibacterial efficacy

NitroPep was applied to a toilet brush to prevent bacterial contamination and aid with cleaning.
The toilet brush is treated with chlorhexidine digluconate which is attached the surface and does not need repeat applications.

The results showed the treated surface killed 99.9 % of bacteria (P. aeruginosa and MRSA) in 5 minutes and 99.9 % of fungi (C. albicans) in 15 minutes.

Tests on NitroPep's technology have been conducted in independent specialist laboratories.

  1. Test methods and protocols have been conducted in line with established industry standards. Tests conducted against S. aureus, P. aeruginosa, MRSA and C.albicans.
  2. Tests were completed on different steel types, different bacteria which are common causes of HAIs and are readily transmissible.
  3. Tests also conducted with splash test surface challenges to replicate and assess impact of hospital cleaning regimes.

The results were outstanding.

Field trials

In situ field testing has been carried out across 24 sites.

These have been tested across the multiple sites in Birmingham including clinical, laboratory, toilet and general meeting areas.

These trials demonstrated greater than 99% efficacy over an extended period of time.

NitroPep has partnered with leading metal processing experts Rübig


Rübig’s low temperature vacuum plasma cleaning technology removes all traces of surface contamination to ensure that their subsequent PACVD plasma activation enables pre-cursor molecules to be bonded to the surface of components, ensuring permanent attachment of NitroPep’s patented antimicrobial technology. NitroPep and Rübig have signed an exclusive licence partnership to work together to further develop and expand this exciting technology.
